patellar ligament rupture reconstruction

After the fracture of the fresh or old patellofemoral ligament, it is often not directly repaired. It is necessary to perform a 1/3 bone--bone tissue transplantation in the middle of the iliac crest, which is called patellofemoral ligament reconstruction. Treatment of diseases: ligament injury, rupture Indication The patellofemoral ligament is broken by an external force. Contraindications 1. There has been a significant change in osteoarthritis in the knee joint: the femoral condyle becomes flat, the joint space becomes narrow or even disappears, and the tibial plateau degenerates. 2. Lower extremity line is not normal, knee varus or valgus - force line correction surgery must be performed before meniscus transplantation. 3. Knee instability - appropriate treatment should be performed before or at the same time as meniscus transplantation, such as ligament reconstruction surgery. 4. Knee joint fibrosis, reflex sympathetic malnutrition or severe pain symptoms. 5. There has been a history of knee infections. 6. Obesity. 7. Severe muscle atrophy in the lower extremities. Preoperative preparation The patellar ligament rupture can be repaired and reconstructed in the next stage of steel wire reduction. The fresh fracture should be sutured directly to the end as soon as possible. If the fracture, defect or old fracture requires semi-tenon tendon and tendon bundle reconstruction, no preoperative need Traction of the tibia.
